Solve this problem by writing an equation using only one variable. Then write your answer with a complete sentence.
Mairé is thinking of two numbers. The first number is 14 less than the second number. When she adds them, she gets 40. Help her younger sister, Enya, figure out the numbers.
Let the second number be x. Write an expression for the first number in terms of x.
The equation you need to solve is x + (x − 14) = 40.
